Abstract
CÁLCULO E AJUSTE DO EQUILÍBRIO DE SONORIDADE PERCEBIDA E/OU ESPECTRAL PERCEBIDA DE UM SINAL DE ÁUDIO. A invenção refere-se à medição e ao controle do equilíbrio de intensidade sonora percebida e/ou espectral percebido de um sinal de áudio. Um sinal de áudio é modificado em resposta aos cálculos realizados, pelo menos em parte, no domínio de sonoridade (psicoacústica) de percepção. A invenção é útil, por exemplo, em um ou mais: controle de volume de compensação de sonoridade, controle de ganho automático, controle de faixa dinâmica (que inclui, por exemplo, límítadores, compressores, expansores, etc.), equalização dinâmica e compensação para interferência de ruido de fundo em um ambiente de reprodução de áudio. A invenção inclui não somente métodos, mas também programas e aparelhos computacionaís correspondentes.CALCULATION AND ADJUSTMENT OF PERCEIVED SOUND AND / OR SPECTRAL SOUND BALANCE OF AN AUDIO SIGN. The invention relates to the measurement and control of the perceived sound intensity and / or spectral sound balance of an audio signal. An audio signal is modified in response to calculations performed, at least in part, in the domain of perception (psychoacoustic) loudness. The invention is useful, for example, in one or more: loudness compensation volume control, automatic gain control, dynamic range control (which includes, for example, limiters, compressors, expanders, etc.), dynamic equalization and compensation for background noise interference in an audio playback environment. The invention includes not only methods, but also corresponding computer programs and apparatus.
